Signal Class Reference

#include <FWCore/ServiceRegistry/interface/Signal.h>

Detailed Description

Description: A simple implementation of the signal/slot pattern

Usage: This is a simple version of the signal/slot pattern and is used by the Framework. It is safe to call 'emit' from multiple threads simultaneously. Assumptions: -The attached slots have a life-time greater than the last 'emit' call issued from the Signal. -'connect' is not called simultaneously with any other methods of the class.
